Winstrol (stanozolol) is one of the anabolic steroids most often used by women, mainly in the last weeks before a physique show or photo shoot. It has a reputation as a “mild” steroid that hardens the physique without water retention. For women, that reputation is misleading. Stanozolol is a potent androgen, and the masculinizing effects it can cause, such as a deeper voice and clitoral enlargement, can be permanent.
This guide covers what Winstrol is, why women use it, how the doses used in medicine compare with the doses women commonly report, what results are realistic, and what is known about its risks. It is written for education and harm reduction. Muscle & Brawn does not recommend using Winstrol or any other anabolic steroid, but we won’t judge anyone who does, and we would rather they have accurate information.
Key Takeaways
- Winstrol (stanozolol) is a DHT-derived steroid taken as tablets or injections. Women use it mostly for contest prep, for a harder, drier look and more strength, not to build size.
- In medicine, stanozolol was started at 2mg three times a day for hereditary angioedema, then lowered to 2mg a day or less. Commonly reported female doses of 5-10mg a day are at or above that range.
- Virilization (a deeper voice, facial and body hair, clitoral enlargement) is the main risk for women. Voice changes and clitoral enlargement may not reverse after stopping.
- Stanozolol is 17-alpha-alkylated, which strains the liver. In a small trial in men, 6mg a day for six weeks cut HDL (“good”) cholesterol by about a third.
- Winstrol is a poor bulking drug and it does not burn fat on its own. Diet, training and cardio drive most of the visible change.
What Is Winstrol?
Winstrol is the original brand name for stanozolol, a synthetic anabolic steroid derived from dihydrotestosterone (DHT). It was developed by Winthrop Laboratories in the early 1960s. Stanozolol has a long clinical history, mainly in the treatment of hereditary angioedema, a rare genetic condition that causes attacks of severe swelling. It has also been used in veterinary medicine. Winstrol tablets for humans are no longer sold in the US. Our stanozolol compound page covers the drug’s chemistry in more detail.
It comes in two forms:
- Oral tablets: The form most women use. Stanozolol is 17-alpha-alkylated, a chemical change that lets it survive the liver when swallowed and also makes it harder on the liver.
- Injectable (Winstrol Depot): A water-based suspension. It is the same molecule, so it is also 17-alpha-alkylated. Underground injectables come at fixed strengths, which makes the small doses women report hard to measure accurately.
Stanozolol’s commonly cited anabolic rating is 320 and its androgenic rating 30, against 100 for testosterone on both. Those numbers are the source of its reputation as a mild, “female-friendly” steroid. They come from old animal assays and are a poor guide to how a drug affects a woman’s voice, skin and hair. In practice, women commonly report masculinizing effects from Winstrol more often than from Anavar.
How Winstrol Works
Stanozolol binds to the androgen receptor like other anabolic steroids, which raises muscle protein synthesis and helps the body hold on to muscle during a calorie deficit. Because it is already a DHT derivative, it does not convert to estrogen, so it causes no estrogen-driven water retention. It also strongly lowers sex hormone-binding globulin (SHBG), the protein that carries sex hormones in the blood, which can leave more free androgen circulating.
Why Do Women Use Winstrol?
On average, women have far less testosterone than men, along with less muscle mass and more body fat. Building visible muscle and getting very lean is slower for most women, and that is the gap Winstrol is used to close.
Because a woman’s own androgen levels are so low, even a few milligrams of an anabolic steroid is a large change for her body. That is why women report noticeable effects at doses men would consider tiny, and also why side effects appear at those same small doses.
The effects women usually want from Winstrol are:
- A harder, drier look: With no estrogen-driven water retention, muscle looks more defined at low body fat. This is the main reason it is popular in contest prep.
- Strength: Users commonly report strength going up, or at least holding, during a diet.
- Muscle retention: Like other anabolic steroids, it helps preserve lean tissue in a calorie deficit.
- Small lean gains: Some new muscle, but modest amounts.
There is no good evidence that Winstrol burns fat on its own. Women who lose fat on a Winstrol cycle are almost always dieting hard and doing cardio at the same time.
When Do Women Use Winstrol? Cutting, Not Bulking
Most women who use Winstrol take it in the final weeks of a diet, usually before a physique, figure or bikini show. Men use it the same way, typically as part of a cutting stack. Our Winstrol review covers how men run it.
Winstrol is sometimes promoted as a “lean bulking” drug for women. It is a poor fit. It adds little muscle size, and a longer bulking phase means more weeks of exposure, which is exactly what raises the risk of virilization, liver strain and cholesterol damage. A lean bulk works through training and a small calorie surplus, and the drug adds little to that.
Winstrol Doses: Clinical vs Commonly Reported
No clinical trial has tested Winstrol in healthy women for physique purposes. The only established doses come from medical use. The table compares those with what women and men commonly report. None of these figures are recommendations.
| Use | Dose | Duration | Source |
|---|---|---|---|
| Hereditary angioedema, starting dose | 2mg three times a day (6mg/day) | Reduced every 1-3 months once attacks are controlled | Prescribing information |
| Hereditary angioedema, maintenance | 2mg a day, or 2mg every other day | Long term, at the lowest dose that works | Prescribing information |
| Women, physique use | 5-10mg/day oral | 4-6 weeks | User reports |
| Men, physique use | 25-50mg/day oral | 6-8 weeks | User reports |
Two things stand out. First, the doses women commonly report are at or above the clinical starting dose, and the clinical labeling for anabolic steroids already warned that female patients must be watched for virilization. Second, men report doses five to ten times higher, so male cycle advice says nothing useful about what is safe for a woman.
Women commonly report starting at 5mg a day. Reports of voice changes, acne and body hair rise as doses go above 10mg a day or cycles run past six weeks. These are not controlled data, and some women report virilization at the low end. No dose is known to be free of risk.
Dosing accuracy is a real problem too. A 2022 meta-analysis of black-market steroid samples found that about a third were counterfeit and roughly another third substandard (wrong dose or contaminated). A tablet sold as 5mg of stanozolol may contain more, less, or a different steroid altogether.
Virilization: The Main Risk for Women
Virilization means developing male characteristics. It happens when androgens act on the voice box, skin, hair follicles and genital tissue. Despite its “milder” reputation, Winstrol carries a high risk of virilization in women, and it is the main reason any woman should be wary of it.
Signs to Watch For
- Hoarseness or deepening of the voice
- New facial hair (upper lip, chin) and more body hair
- Clitoral enlargement
- Acne and oily skin
- Thinning scalp hair
- Menstrual changes, including irregular or missed periods
What the Evidence Shows
The prescribing information for medical anabolic steroids, stanozolol included, tells doctors to watch female patients closely for virilization and to stop the drug as soon as mild signs appear, because some of the changes are irreversible. That warning applied at the clinical doses in the table above, which are lower than or equal to what women commonly report for physique use.
Studies of women who use steroids for sport point the same way. In a 1985 study in JAMA, ten female weight-trained athletes who used anabolic steroids reported a deeper voice, more facial hair, clitoral enlargement and menstrual changes alongside the strength and muscle gains they wanted. A 2021 Norwegian interview study of women who had used anabolic steroids also documented masculinizing effects, along with menstrual and sexual changes.
Which Changes Reverse?
Acne, oily skin and menstrual changes usually settle after stopping. Voice deepening and clitoral enlargement are often permanent. New facial hair may need laser treatment or electrolysis to remove. The voice is the most common lasting change, because androgens thicken the vocal cords and they do not shrink back.
Shorter cycles and lower doses reduce exposure, but they do not make Winstrol safe. Some women only notice hoarseness once the change has begun. Anyone who notices any of the signs above should stop and see a doctor.
Other Side Effects and Risks
Liver Strain
As a 17-alpha-alkylated steroid, stanozolol can raise liver enzymes and cause cholestasis, a slowdown in bile flow that can lead to jaundice. Long-term use of this class of steroids has been linked to peliosis hepatis (blood-filled cysts in the liver) and liver tumors. The risk rises with dose, duration, alcohol and other oral steroids.
Cholesterol and Heart Health
Stanozolol is one of the harshest steroids for cholesterol. In a small 1989 trial in male weightlifters, 6mg of oral stanozolol a day for six weeks lowered HDL (“good”) cholesterol by about 33% and raised LDL by about 29%. In the same trial, 200mg a week of injectable testosterone lowered HDL by less than 10%. There is no equivalent study in women, but 6mg a day is in the range women commonly report.
Hormonal and Menstrual Disruption
Anabolic steroids suppress the brain signals that drive the menstrual cycle. Irregular or missed periods are common, and fertility can be affected for some time after stopping. Stanozolol must not be used during pregnancy, because androgens can masculinize a female baby.
Joints, Hair and Skin
Users commonly report dry, achy joints on Winstrol. This comes from user reports, and the cause is not well understood. As a DHT derivative, stanozolol can also thin scalp hair in women who are prone to hair loss, and it can trigger acne.
Winstrol vs Anavar for Women
Anavar (oxandrolone) is the steroid most often compared with Winstrol for women. Both are DHT-derived, both are 17-alpha-alkylated orals, and neither converts to estrogen. Users consistently describe Anavar as the lower-risk option of the two for virilization.
| Winstrol | Anavar | |
|---|---|---|
| Forms | Oral or injectable | Oral only |
| Anabolic / androgenic rating (commonly cited) | 320 / 30 | 322-630 / 24 |
| Commonly reported female dose | 5-10mg/day | 5-10mg/day |
| Liver strain | Significant (17-alpha-alkylated) | Moderate (17-alpha-alkylated) |
| Effect on HDL cholesterol | Strong reduction | Reduction |
| Virilization risk (user reports) | Higher | Lower, but present |
| Joint discomfort | Commonly reported | Rarely reported |
Lower risk is not no risk. Anavar can also cause permanent virilization, and it also lowers HDL. Our guides to Anavar for women and Anavar vs Winstrol compare the two in more depth.
Diet, Training and Cardio Matter More
No steroid makes up for poor diet or training, and Winstrol is no exception. For most women, the habits below produce nearly all of the visible change, with or without a drug.
Diet
Getting lean takes a steady, moderate calorie deficit. Eat plenty of lean protein, get fats from whole foods such as fish, eggs, nuts and olive oil, and get most carbs from minimally processed sources like oats, rice, potatoes and fruit. Fill the rest of the plate with vegetables. Alcohol slows fat loss, and with a 17-alpha-alkylated steroid it adds load to the liver as well.
Cardio
Cardio raises daily energy use and supports heart health, which matters more when a drug is pushing cholesterol the wrong way. Walking, cycling, swimming, rowing and intervals all count. The best option is the one you will keep doing consistently.
Training
Lift weights regularly and train every major muscle group at least once a week, ideally twice. Add weight or reps over time, keep good form, and push sets close to failure. How you split the week matters less than doing it consistently.
Who Should Avoid Winstrol?
Winstrol is not recommended for:
- Women who are pregnant, breastfeeding, or trying to conceive
- Anyone prone to hormonal imbalances, including women with conditions linked to high androgen levels such as PCOS
- Women with liver conditions, high cholesterol or heart disease
- Anyone whose work or life depends on their voice, since voice changes may be permanent
- Athletes who compete in tested federations
- Anyone not fully informed about the risks of virilization
For anyone who uses it despite the risks, blood work for liver enzymes and cholesterol before and after a cycle is the only way to see what it is doing internally. Stopping at the first sign of virilization is the only way to limit permanent change.
The Bottom Line
Winstrol can make a lean physique look harder and stronger, but for women its “mild” reputation hides a high risk of permanent virilization at the very doses women commonly report.
- Commonly reported female doses of 5-10mg a day are at or above the clinical dose, and voice deepening and clitoral enlargement may not reverse after stopping.
- It is hard on the liver and on cholesterol: in a small trial in men, 6mg a day for six weeks cut HDL by about a third.
- It is neither a bulking drug nor a fat burner. Diet, training and cardio drive most results, and Anavar is generally reported as the lower-risk option, though not a safe one.
